Shadow ONLY Shader in URP 12.1.6 & Unity 2021.3.0+

[Ruhan]

Just as the title says, I just need a simple shader to apply on a Quad on the ground so that it simply shows the shadow received only WITHOUT mesh or shadow casting.

I have gone through the following forums but something in URP changed again and there is no way to obtain this…

How to make Receive shadow shader in URP

So I fallowed the Unity manual Unity - Manual: Custom shader fundamentals , section “Receiving shadows”. And it works well. But I want TODO the same thing in URP, but it simply not working with this code. Here is my try until now: Shader "Unlit/Kaka" { Properties { _MainTex ("Texture", 2D) = "white" {} } SubShader { Tags { "RenderType"="Opaque" "RenderPipeline" = "UniversalPipeline" } LOD 100 Pass { Tags{ "LightMode" = "U…

URP Unlit shader that receives shadows exclusively from other objects?

As of 2020, is there a way to prevent an object from drawing its own shadow while still drawing everything else from the shadowmap?

Water shader graph: Transparency and shadows / universal render pipeline order

Hi, I could use some help with a shadow+transparency related problem. I’m working on a water shader graph with the universal render pipeline in unity 2019.3.0b3. Since I wan’t the water to be partly transparent I have set the surface property of the PBR Master to transparent. This however seems to disable zwrite for the water layer (in my case a sphere). Is there a way I can enable zwrite, but still have the transparency? Or is there a way to render the water layer after the shadows? [4984…

Matte Shader (Only Shadows) in HDRP

Hi everyone, I’m using HDRP for my current project and I need to cast a shadow on a transparent plane. So far I found quite a bunch of tutorials on how to do that using regular Unity shaders in SRP, but none for HDRP (preferably using default shaders or Shader Graph). Thanks for your help!

This is the only poor hack I was able to find by experimenting but it still multiplies the colors behind it. There are no combination of settings to my knowledge that allows alpha 0 while showing shadows properly.

With URP 3.1.8 I get this error when I import the package: Shader error in 'Shader Graphs/ShadowReceiver': Couldn't open include file 'Packages/com.cyanilux.shadergraph-customlighting/CustomLighting.hlsl'.
Can anyone help?

I’d recommend updating to Unity 2021. URP 3.1.8 is very outdated.
As per your problem, the github root directory has the CustomLighting.hlsl file that the shader is complaining about. Move it to a new directory like root Asset folder and change that line in the shader file to point to ‘Assets/CustomLighting.hlsl’ instead of ‘Packages/com.cyanilux.shadergraph-customlighting/CustomLighting.hlsl’

Hi, unfortunately this method is only for directional light. How do I support other lighting sources?

My shadow receiving asset just added support for additional lights.
You can modify the custom lighting linked above to achieve a similar result as well, but that requires some shader knowledge

This doesn’t really work for me, any idea why?
I’ve created a quad, added a material that uses the ShadowReceiver shader, and all it does is make the object transparent. I’ve tried a directional light and a spot light, nothing really helps.
